Battery Boost Switch:
The Battery Boost switch engages a heavy-
duty solenoid to electrically connect the house
batteries to the engine battery in the event
the engine will not crank or cranks slowly.
The solenoid is designed for short-term high
current intermittent use. Engaging the boost
solenoid for an extended period will damage
the solenoid.
Jump Starting Using the Battery Boost
Switch:
With the ignition key OFF,

press and hold the Battery
Boost switch for ten seconds.
After ten seconds, continue to
hold the switch down and turn
on the ignition.
If the engine fails to crank or

does not crank fast enough,
discontinue the attempt.
Continued attempts will only diminish
any remaining surface charge in
the chassis battery and end future
alternative attempts.
Next, start the generator. This may

require using the Battery Boost switch
for the generator to start from the
engine battery. Once the generator is
operating, the electrical combination
of the generator and the inverter will
charge the batteries.
Allow the generator to run

approximately ½ hour before
attempting to start the engine.
080349
After ½ hour of generator operation,

leave the generator on and hold down
the Battery Boost switch for one
minute. Release the switch for one
minute, then press the switch again for
one minute. Alternate this cycle three
to five times.
Next, hold the switch down and turn

the ignition ON. The battery voltage
gauge should indicate at least 12 Volts.
If voltage is sufficient with the Boost
switch held down, try to start the
engine.
If the engine fails to crank, or fails to

crank quickly, the chassis battery may
be depleted and the motorhome will
require jump-starting or an external
charger hooked to the chassis battery.
Jump Starting Using an External Source:
When using jumper cables to start the
080349
engine, the cables must connect in a parallel
On Dash
configuration. That is, positive (+) to positive
and negative battery (-) to negative chassis
(-). Always connect the positive (+) before
connecting the negative (-). To prevent arcing
when disconnecting the cables; disconnect the
negative (-) before disconnecting the positive
(+).
WARNING
Always ventilate the battery
compartment prior to any work or
service to the batteries. Gas emitted
by the batteries can explode when
exposed to smoking material, flames,
sparks or other sources of ignition,
resulting in injury or vehicle damage.
Batteries contain sulfuric acid that can
burn skin, eyes and clothing. DO NOT
connect the end of the second cable to
the negative (-) terminal of the battery
to be jumped. Connect only to the
chassis, away from the battery.
CAUTION
A large amount of electrical current
is required to jump-start an engine.
The sizes of the battery, alternator
and jumper cables supplying the
"jump" are current limiting factors.
Wait a sufficient amount of time
for a surface charge to build before
attempting to start the engine. Voltage
fluctuations that occur during a
jump-start procedure can damage
sensitive electronic equipment and
charging systems. If a jump-start is
necessary, it is recommended to call
Roadside Assistance. They will have
the equipment necessary to jump-start
the motorhome.
